Embodiment Construction

[0014] Such as figure 1 The schematic diagram of the claw engine power generation cycle device for the thermal power generation system shown includes a heater 1 , a check valve 2 , a claw compressor expander 3 , a generator 4 , a regenerator 5 and a cooler 6 . Its working process is: after the gas is compressed by the claw compressor in the claw compressor expander 3, it enters the heater 1 to absorb heat, and enters the claw expander in the claw compressor expander 3 to expand and perform external work. The expanded gas enters the regenerator 5 for heat release, the temperature of the gas decreases, and then enters the cooler 6 to be further cooled, and the cooled gas enters the claw compressor in the claw compressor expander 3 for compression; The compressed gas enters the regenerator 5 to absorb the heat of the expanded gas, and then enters the heater 1 to absorb heat so that the temperature rises again, and the gas after absorbing heat enters the claw compressor expander 3...

Abstract

The invention discloses a claw type generator power generation circulating device for thermal power generation. The claw type generator power generation circulating device consists of a heater, a one-way valve, a claw type compression expander, a heat regenerator, a cooler and a generator, wherein the claw type expander comprises a claw type compressor and a claw type expander. The power generation work circle comprises an expansion process of gas in the claw type expansion machine, an isobaric heat release process of the gas in the heat regenerator, an isobaric heat release process of the gas in the cooler, a compression process of the gas in the claw type expander, an isobaric heat absorption process of the gas in the heat regenerator and an isobaric heat absorption process of the gas in the heater. A claw type compressor rotor and a claw type expander rotor are coaxially connected in series to form the claw type compression expander which can realize multi-stage compression and multi-stage expansion; and the claw type compressor rotor and the claw type expander rotor in each stage respectively adopt sharp point-free circular arc claw type rotor molded lines; and phases of the claw type compressor rotor and the claw type expander rotor in each stage are uniformly distributed on the circumference. The claw type generator power generation circulating device is suitable for application occasions of solar thermal power generation and industrial waste heat power generation.

Description

technical field [0001] The invention relates to an engine generating cycle device for generating electricity by utilizing thermal energy, in particular to a claw type engine generating cycle device for thermal power generation which adopts a claw compressor and a claw expander. Background technique [0002] The use of solar energy and industrial waste heat for thermal power generation has broad application prospects. Thermal power generation uses engines to convert thermal energy into mechanical energy and drive generators to generate electricity. Existing thermal engines mainly include: steam turbine power generation cycle and Stirling power generation cycle; the steam turbine device is huge and suitable for high-power power generation; the realization of the Stirling generator is relatively difficult. Due to the increasing number of applications for thermal power generation, it is of great significance to propose a new engine power generation cycle device for thermal power...
